The first decoding of essentially ALL the text in SMTIV's (English localized) script has been released!! (FYI, as it is an M-rated game, do proceed with caution. Spoilers also, but you knew that.)
You can download the .txt files for offline reading OR you can just flip through them in the repository (or download the one BIG one and ctrl + f around). Either way, I hope this provides a good resource for fans of the game, writers/artists, or folks who just love info and want to know more.
Included as well is a program to decode SMTIV's .mbm files into .txt if you'd like to do it yourself.
Full creds to @affinity-for-beans for the programming and decoding- i.e. the important bit. All I did was help with context and write the README. And edit the silly image up top.
It's not perfect, of course, but I hope this text repository keeps the knowledge of this extremely underrated 3DS game alive.
